MACHINE FOR FORMING BUTTER-FATS.

Specification of Letters Patent.

Patented March 80, 1909.

Application filed May 26, 1908. Serial No. 435,116.

T 0 all whom 'it may concern:

Be it known that I, ISAAC Soon, a citizen of the United States, residing at Washington, in the District of Columbia, have invented a new and useful Machine for Forming Butter- Pats, of which the following is a specification.

My invention relates to machines for forming butter pats, and has for its object to revide a machine of this kind which wil be continuous in operation; which is convenientl operated and easily cleaned; which will e eflicient in action and which will not get out of order.

For these and still other objects, which will hereinafter a pear, my invention consists of certain nove features, arrangements and combinations of parts, of which the herein described machine is one of many possible embodiments.

While herein I have described minute details of my invention, I do not limit myself to these as the details of construction and combination may be greatly varied without departing from the spirit and scope of the invention.

In the annexed drawings forming a part of this specification, which are for illustrative purposes only, and therefore not drawn to any particular scale and in which like reference characters refer to like parts throughout the several views, Figure 1 is a longitudinal vertical sectional view of my machine as it is assembled when it is in operation; Fig. 2 is a top plan view of the same; Fig. 3 is a transverse vertical sectional view taken on the line 3-3 of Fig. 1; Fig. 4 is a rear end view, and Fig. 5 is a perspective view of a detail.

The machine is provided with a base or support 1 having a rear standard 2 and a pair of u wardly and forwardly pro ecting arms '3, t e u per ends of said arms being turned inward y to meet and form a supporting bar 4 carrying a bearing box or bore 5. The end of the device carrying said box or bore 5 will be hereinafter considered the forward or outer end of the machine.

The rear standard 2 is provided at its upper end with a semicylindrical head 7 having a laterally projectin arm or lug 3 to which is hingedly connected as at 9 a similar arm or lug carr g a movable head 10 ada ted to be close 11 on the head 7. The hea s 7 and 10 are eac provided with semicylindrical threaded grooves 11 and 12 cooperating,

when said heads are closed u )on each other, to form. a threaded bore for t ie reception of the threaded rod 13. i

The rod 13 and the slipshaft 14 indirectly support the cylindrical vessel 15 as will be presently explained. Said vessel is rovided at the forward end with a removab e cap or bottom 16 having a rearwardly projecting annular flange 17 adapted to embrace the forward end of the vessel. Small pins 18 rigidly secured in the forward edge of the vessel 15 engage shouldered notches 19 in the flange 17 to removably hold said cap upon the vessel. The cap 16 is provided with a central outwardly opening bore 20 adapted to snugly receive the inner end of the slipshaft 14. A projecting crosspin 21 engaging corresponding radially projecting slots 22 communicating with the bore 20 constrains the cap 16 to rotate with the slipshaft 14. Conveniently placed between center and circumference of the cap 16 is a convenient number of holes or openings 23 preferably arranged in an annular series concentric with the cap 16. I have illustrated three of these holes or openings 23 as being the most convenient number, but I do not limit myself to any particular number or size or shape for these openings. The rear end of the vessel 15 is fitted with a removable spider having a central hub 24 having therein a smooth. bore 25 adapted to receive the screw rod 13. The arms of the spider support a flanged rim 26 adapted to embrace the rear of the vessel 15. Means as, for instance, the pin and notch at 27 constrain said vessel and said spider to rotate together.

The heads 7 and 10 are provided at their inner ends with countersunk recesses 23 together forming a bearing seat for the reception of the hub 24 when said heads are closed against each other.

The slipshaft 14 has rigidly secured thereto a stop collar 29 which may be contacted by a block 30 pivoted by means of a rivet 31 to the bar 4. The free end of the block 30 and the free end of the head 10 are connected by a bail handle 32 by means of which said head 10 and said block may be simultaneously moved to open position, or be caused to engage said rod 13 and said collar 29 respectively.

The bore 25 is provided with a longitudil nally disposed lug 33 adapted to slidably engage a groove or seat 34 extending substan- Ill) tially the length of the rod 13. It will be seen that said last named lug and groove cause said rod to rotate with said spider. The inner end of the rod 13 has rigidly secured thereto the disk like follower or plunger 35.

The forward end of the base 1 is provided with a forwardly projecting pin 36 having a rear enlargement 37. Said pin has pivotally mounted thereon a cutting attachment comprising a cutting frame 38 carrying a cutting wire 40 adapted to be moved across the opening 23, and a cam lever 41 carrying a roller 42. A spring 43 coiled around the pin 36 and having one end secured to the enlarged portion 37 and the other bent under the lever 41, serves to press the roller 42 upwardly against the laterally projecting cam flange 44 of the cap 16.

A crank 45 or other means of rotation is provided for the slipshaft 14.

The operation of the machine is as follows: The cap 16 is placed on the vessel 15 and the butter to be formed into pats is placed in said vessel. The rod 13 is slipped to bring the disk 35 near the hub 24 of the spider. The spider is then placed upon the vessel 15 and the hub 24 placed in the countersunk recess 28 of the head 7. The slipshaft is then rotated until the pin 21 registers with the slots 22 and the slipshaft then moves into the recess 20, the pin 21 engaging the slots 22. The bail handle 32 is then moved down causing the block 30 to engage the collar 29, thus holding the slipshaft and the pin 21 in engagement with the bore 20 and the slots 22 of the cap 16, and causing the threads of the heads 7 and 10 to engage the threads of the rod 13. With the parts in place as thus described, it is only necessary to rotate the crank forwardly, and the action of the screw rod 13 as said rod rotates will cause the follower 35 to force the butter out through the holes 23. As the butter is being thus forced out the wire 40 remains, for a part of the time, between the holes 23, as shown in Fig. 3. As one of the holes 23 advances toward the Wire 40 the roller 42 passes into the depression in the cam flange 44. Thiscauses the wire 40 to recede before said hole 23 until the roller rides out of said depression and causes the Wire to move quickly across the hole thus cutting off a pat or tablet of butter. The pats thus formed may be allowed to drop into a suitable receptacle. Continued rotation of the crank handle repeats this operation until the desired number of pats is formed or until the butter in the vessel is exhausted.

It will be readily seen that the various parts of the machine may be easily separated for cleaning.

Any suitable metal or material may be used in the construction of this machine.

It is thought that the operation and advantages of this machine will be understood without further explanation.
